Economy is the controlled implosion of conceived value, via the infinite blueshift of idle want, within a social Schwarzschild wormhole that terminates with one's person.
You always come back to the idiotic theme of the only economy is no economy, i.e. man is an island.
Even the Bible recognizes for example in the Parable of the Talents that not conducting trade and commerce is more evil than burying your talents (capital or shekels) in a hole.
The following explicitly argues against producing everything yourself and instead build economies-of-scale and trade:
Leviticus 19:19 Ye shall keep my statutes. Thou shalt not let thy cattle gender with a diverse kind: thou shalt not sow thy field with mingled seed: neither shall a garment mingled of linen and woollen come upon thee.
